M8091BSPA
IEEE 802 3bs Pre-Compliance Receiver Test Application
Key Features
Description
The M8091BSPA receiver test application is designed to assist and simplify the stress signal calibration used for testing the inputs of 200GAUI-4 and 400GAUI-8 PAM4 capable hosts and modules. It reduces user interaction to a minimum and performs all required calibration routines and compliance testing automatically by remote controlling all required instruments. The test application utilizes the same frame work for the graphical user interface like most of Keysight transmitter test applications reducing training time by providing a common look and feel. When a user is required to perform setup changes, the user is guided by diagrams as well as text to minimize errors. The respective clauses and annexes of the IEEE 802.3 specification which were added during the IEEE 802.3 bs project for 200GbE and 400GbE define the stress signal through a mated host compliance board (HCB) and module compliance board (MCB) connection. Both the receiver side as well as the transmitter side do have equalization capabilities. The definition of the stress signal assumes an optimized link. Therefore, the transmitter of the receiver test equipment as well as the receiver of the signal measurement device must be optimized for the given stress channel. This must be done iteratively for each test setup. The standard requires the transmitter equalization (TxEQ) to be kept as small as possible to increase the stress on the device under test’s receiver (DUT RX). This process is very time consuming. The M8091BSPA Receiver test application performs this task automatically. Results of the individual calibration steps and tests are presented in tabular form as well as graphical form where appropriate. Calibrations and test results can be stored in projects and recalled at a later point in time. The application can generate an HTML based test report.
Calibrations and Tests Covered by M8091BSPA Pre-Compliance Receiver Test Application
All calibration steps are automated. The test application prompts the user when user interaction is required for connecting the test setup. Detailed connection diagrams and instructions are provided by the test application.
